Abstract
An optoelectronic device including a support, at least a first conductive layer covering the support, display pixels including first and second opposite surfaces, bonded to the first conductive layer, each pixel including an electronic circuit including the first surface and a third surface opposite to the first surface, the first surface being bonded to the first conductive layer, and an optoelectronic circuit bonded to the third surface and including at least two light-emitting diodes, at least one of the electrodes of each light-emitting diode being connected to the electronic circuit by the third surface, the optoelectronic circuit further comprising photoluminescent blocks covering the light-emitting diodes and conductive or semiconductor walls surrounding the photoluminescent blocks, and at least one second conductive layer electrically coupled to at least one of the pixels.
